The impact of the economy should not have any different effect on a NNN owner versus one who employs a gross lease. With a gross lease you are building the cost of taxes insurance and maintenance into the "base" lease rate and passing through any increases to a tenant. At the end of the day its semantics.I have heard of some landlords who will provide a true gross lease and not pass through any increases, but it is silly to absorb that risk. Think of insurance rates after 911.
